mediumCVSS 4.3CVE-2026-67439

OliveTin gives safe and simple access to predefined shell commands from a web interface. Prior to 3000.17.0, the service/internal/api/api.go StartActionAndWait and StartActionByGetAndWait endpoints return full LogEntry output after execution without enforcing the logs permission, allowing a user with exec permission but logs:false to read action output. This issue is fixed in version 3000.17.0.
